How to Test Ketones

If you aren’t getting the results you want with the keto diet, you might not be in ketosis… yet. You can test your ketones to confirm this, and you’ve got two options: a blood test or a urine test.

Urine tests tend to less invasive and more affordable, but they aren’t always as accurate as a blood test – especially if you’re dehydrated. If you’re committed to checking your ketones regularly, a blood test can accurately detect beta-hydroxybutyrate (BHB), a ketone that your body makes and then converts into energy.
